Common Questions and Issues

How can I default (factory reset) my phone?

For Mitel phones: Dial ∞+394 (or Ⓧ+394). Look at the display and verify the display says STATION DEFAULTED. This will reset the phone to the factory settings.


For Yealink phones:  If you ever find yourself locked out of a Yealink phone, and do not know the admin password, you can quickly reset the phone to
Factory Default Settings.

1.Simply press and hold the ‘OK’ key on the face of the phone for 10 seconds – as shown below:

2.This will prompt you to accept or decline a factory reset.  

 3.If you accept, the unit will restore itself to factory default settings – without the need the admin password.

4.The entire process takes roughly 30 seconds. 

How can I change the date/time?

From the administrative phone only, dial ∞+9800 (or Ⓧ+9800) and follow prompts.

How can I change my greeting?
From the phone, dial 2500 and press * once the prompt start. Follow the prompts, including inputing the extension of the phone whose greeting you wish to change.
How can I access my voicemail?
From the phone, press the message key and follow the prompts. If you’re calling in from somewhere else, dial the main number and as soon as the greeting starts dial *. Follow the prompts.
I can't be heard/the other party can't hear me.
First, default the phone. If this does not work, try switching out the handset or handset cord. If this still does not work, then seek further assistance.
There is no dial tone.
Look at the display to ensure that it displays your extension number and the date & time; if the display is blank, then there is no power going to the phone. Test to see that if you can speak with another extension; if you can, then this indicates that the system is working, but the outside service is not working. If this still does not work, then seek further assistance.
